Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a module for electrical contacts, and more particularly to a housing with a catch for housing at least one electrical contact, and a module rotatable relative to the module. The state of being closed at the same time as being supported by means of the electric contact module indicates that the contact is locked.

2. Description of the Related Art Application filed on January 8, 1993,
French patent application 2518780 by SA Francelco discloses a module of the same kind.

In the structure disclosed in the above-mentioned document, as shown in FIG. 7 of the document, element number 56, the lid is formed of an elongated elastic member, and an insulator is attached to the box-shaped module. It is configured so that both ends thereof can be fixed when inserted. The elongated elastic member is provided at a position facing a fixing member 50A for fixing the electric contact.

[0004]

When the contacts are not fixed in the correct position, the lid is not completely closed.
It becomes difficult to house the module in the casing.
However, in reality, since the lid of the module and the wall surface of the casing are elastically deformed, it is possible to store the module in the casing even when one or more contacts are not properly fixed.

An object of the present invention is to provide a contact module that does not cause the above problems.

[0006]

According to the present invention, the above object is achieved by forming a locking member on the contact-side surface of the lid that can be opened and closed. An elongated fastener is provided on the contact side of the openable lid to allow secondary retention. According to a preferred embodiment of the present invention, the hinge portion is a portion having a smaller thickness than the vicinity thereof, and one end of the hinge portion is attached to the end portion of the lid and near the center in the thickness direction of the lid. The module has a plurality of contact housings for housing a plurality of contacts, and a common lid that can cover at least some of the housings. The present invention is
Also provided is a connector having a casing that houses at least one of the modules. The casing has a portion which, when the lid of the module is not closed, abuts against the lid and prevents the module from being completely inserted.

Other features and effects of the present invention will be apparent from the description of the embodiments given in the following paragraphs and the accompanying drawings.

1 is a perspective view showing a preferred embodiment of a contact module according to the present invention. FIG. 2 is a perspective view of the contact module shown in FIG. 1 viewed from another angle. 3A to 3C are cross-sectional views of the contact module and the casing according to the present invention. FIG. 3A shows a state where the module lid is not closed,
FIG. 3 (b) shows a state in which the lid abuts on the casing, and FIG. 3 (c) shows a state in which the module is correctly accommodated in the casing.

As shown in FIG. 1, a contact module 10 according to the present invention has a flat plate 14 and a partition plate 12 forming an accommodating portion 11 having a substantially rectangular cross section. A cover 71 is provided facing the flat plate 14 so as to cover a part of the housing portion, and a part of the cover 71 has a pressing member 73 extending so as to approach the flat plate. The holding member 73 narrows the width of the housing portion 11 by the holding portion 75. Further, in the opposite direction, a hinge portion 76, which is thinner than the central portion of the cover 71, is connected to the vicinity of the central portion of the end portion 100 of the lid 77 in the thickness direction. Inside 78 of the lid 77
A locking portion 79 is provided at a position facing the contact member 1 to indicate that the contact member 1 is held at a predetermined position and to perform secondary pressing.

A ridge 80 is formed on the base of the lid 77 near the hinge portion 76, and the ridge protrudes from the outer surface of the module in accordance with the movement of the hinge.

The contact member 1 has a head portion 2 having two parallel side surfaces 24 facing the dividing plate 12 and a surface 22 parallel to the lid 77. The head 2 has an end 21. Head 2
The rear end surface 25 is housed in the area 3 protected by the lid 2. The area 3 is the vertical surface 3 of the rear end surface 25 and the intermediate portion 33.
1 and the area 4 surrounded by the front or rear surface 42 of the area 4 and further connected to the member 5 that houses the end of the cable 6.

The parallel plane 22 of the head 2 is formed by the pressing member 7.
It has the engaging portion 23 with which the pressing portion 75 of 3 is engaged. The accommodation portion 11 is provided with a fastener 85 that comes into contact with the head and partially closes the accommodation portion from below the accommodation portion.

The state in which the contacts are inserted into the contact module and the casing is shown in FIGS. 3 (a) to 3 (c).

FIG. 3A shows a state in which the contact 1 is inserted halfway and the parallel surface 22 blocks the movement of the protrusion 79 of the lid 77. In this state, the lid 77 projects from the hinge body 76 from the module main body, so that the module cannot be inserted deeper into the casing 9. The ridge 80 contacts the upper end of the outer wall 93 of the casing, and the hinge 76 elastically deforms so that the lid 77 is parallel to the insertion direction. However, since the protrusion 79 contacts the head of the contact, the lid 77 cannot be pushed into the inside of the outer wall 94 of the casing 9 (FIG. 3B).

In the embodiment shown above, the lid 77
Is common to all contacts 1, so all contacts 1
The lid 77 cannot be completely closed until after the insertion has been completed. In this state, the pressing member 75 of the pressing portion 73 engages with the engaging portion 23.

As shown in FIG. 3 (c), when the contact module is completely inserted in the casing, the bottom portion 85 of the module contacts the portion 91 of the casing 9 and the bottom surface 21 of the contact 1 is located at the bottom portion of the module. Contact with the upper surface of 85.
